推荐答案

如果您关注mvvm设计模式有这样的步骤：

1.在你的userControl模型中创建一个属性并将其命名为ControlId。

2.将userControls添加到某个变量：例如List或ConcurrentBag或其他什么。

3.将此绑定到您的视图（MainWIndow）。

4.在MainWIndowViewModel上实现事件以检查userControls。



示例：

YourUserControlModel.cs：

If you are following mvvm design pattern there are such steps:
1. In your userControl model create a property and call it ControlId.
2. Add userControls to some variable: for example List or ConcurrentBag or whatever.
3. Bind this to your view(MainWIndow).
4. Implement Event on your MainWIndowViewModel to check for userControls.

Example:
YourUserControlModel.cs :

public int ControlId{get;set;}

设置此属性的某处。

在构造函数中加载用户控件，如下所示：

Set somewhere this property.
Load your usercontrols in constructor like this:

public MainWindowViewModel()
{
    Controls.Add(new YourUserControl());
}

private readonly DeferrableObservableCollection<YourUserControl> Controls = new DeferrableObservableCollection<YourUserControl>();

查找userControls的事件：

Event to look for userControls:

void SomeName(object Sender, EventArgs e)
{
   foreach(var control in Controls)
   {
       if(control.ViewModel.Model.ControlId == 1) // checks, if collection has userControl with id 1. And so on for all controls
       
   }
}

希望这对你有帮助。
